To all whom it may concern:

Be it known that I, RUSSELL B. a citizen of the United West Oran e, in the county of Essex and State of ew Jersey, have invented certain new and useful Improvements in Cleaning Pads and Methods of Producing the Same; and I do hereby declare the following to be a full, clear, and exact descrlptlon of the invention, such as will enable others grammatic perspective of a sheet of material ready for the necessary manipulation involved in the novel method of producing the finished cleaning pad; Figure 2 shows the first step in the manipulation of the sheet material to produce the novel cleaning pad; Figures 3 to 10 inclusive show in diagrammatic perspective the various successive steps 0 the method of producing the novelcleaning pad; Figure 11 is an end view of the initla ly formed material resulting from a performance of the method steps shown in Figures 3 to 10 inclusive; Figure 12 is a diagrammatic pers ective view of the final method step whereby the completion of the interfolding and convolving of the sheet material is accomplished to complete the novel form of cleaning pad; Figures 13 to 18 inclusive are diagrammatic cross sections showing various stages of the method in volving the rolling or convolving of the initial sheet material into final form; Figure 19 is a dperspective view of the novel cleaning pa as it approaches completion, and Figure 20 is an end view of the same; Figure 21 is a side elevation of the completed cleaning pad, and Figure 22 is an end view of said completed cleaning ad.

Similar c aracters of re erence are employed in all of the hcreinabove described views, to indicate corres ondin parts.

In making up the nove cleaning pad embodying the principles of this invention, I take a flat rectangular sheet a ofa suitable flexible material, as shown in Figure 1. The material selected for the purpose may be one of a variety of flexible sheet materials ac cording to th character of finished article desire For example, if it is desired to produce a finished spongiform cleaning pad or device ada ted to provide a maximum of abrading act10n when the same is applied to a surface to be cleaned, an all metal abric, that is one produced by interwoven or knitted metallic strands, may be employed. If a milder abrading action is desired, a composite fabric of suitably combined metallic and vegetabl yarn strands may. be employed. If a soft spongiform mass is desired, a fabric composed solely of vegetable 1 KINGMAN, States, residing at make and use the same, reference being bad to the accom anying drawings, and to characters of re erence marked thereon, whlch form a part of this specification.

This invention relates, generally, to an 1mprovcd construction of resilient c caning device or ad, and to a novel method of producing t e same.

The invention has for its ob ect to provide a novel construction of c caning device or pad in the form of a resilient substantiall cylindrical mass adapted to be produce from a suitable sheet material such as fibrous fabric materials, animal sk1ns, metallic fabrics, or composite metallic and vegetable arn fabrics; and the invention has for a urther ob set to provide a novel and easily performed method of producing the aforesaid novel construction of cleaning device or pad.

To the above ends this invention comprises a novel interfoldcd and convolved mass of base material, so wrought into shape as to interlock its folds and convolutions to produce a substantially cylindrical resilient or soft mass, adapted to readily retain its shape under wear, without likelihood of unraveling or becoming stringy, with conscqucnt loss of appearance or of comfort in handling when using the same.

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.

In the accom anying drawings, the va rious steps invo ved in the method of making the novel cleaning pad, as well as the finished article itself, is clearly illustrated.

In said drawings, Figure 1 shows a diaor other suitable yarn may be employed; and if a substantially non-abrading or so polishing action is desired, the material employed in producing the novel cleaning ad may comprise a soft and flexible animals in,

such as chamois.

The first step in (producing the novel cleaning pad is to fol the sheet material a diagonally upon itself, thus producing the diagonal fold b shown in Figure 2, with the free corners 0 of the sheet material registered together and overlying one upon the other. When the material has been thus folded upon itself I start at the dia nal fold b, and roll the material upon itse f toward the free corners 0, as shown in Figures 3, 4 and 5, thus producing an elongated roll of the material, with the corners 0 uppermost and intermediate the ends (I and e. I next take the end (i and fold the end portion of the elongated roll of material longitudinally upon itself, bringing the said end d over upon the free corners 0, thus producing a transverse fold f, as shown in Figure 6. Thereupon the transverse fold f is turned upwardly and over to again fold the rolled material longitudinally, with said fold f arranged above the end (I, thus forming a double transverse outer fold g, as shown in Figure 7. I next take the opposite end 6 of the rolled material and inwardl fold the same over to meet the fold f, an thus producing a transverse fold h, as shown in igure 8, thereu on taking the transverse fold h and inwar ly folding the same over toward the opposite fold g, and producin an opposite double transverse outer fol a, as s own in'Figures 9 and 10. The material when thus far manipulated produces a roughly elongated mass with a plurality of inturned layers of the rolled material piled above the free corners 0, which leaves substantially smooth end portions formed by the respective outer folds g and i, and as indicated by the end view shown in Figure 11. The free corners 0 will thereupon lie between the intermediate body 9' of the rolled material and the said interfolded layers, with the ends d and e inwardl disposed and concealed, said interfolde layers being thus arranged to be interlocked into the final finished article so as to form the center core is thereof. Having completed the above described manipula tions of the material to produce the initially rolled and folded body, I thereupon hold the corners 0 against the interfolded center core is, and then grasping the outer portion of the intermediate body I roll or turn the core is and intermediate body j in opposite directions, as indicated by the arrows in Figure 12. This turning movement unwinds the convolved intermediate body 9' and reverses the same so that it is caused to be convolved exteriorly and longitudinally around the center core is, while at the same time twisting and interlocking the junctures of the respective ends of said core and intermediate body j, as shown at 1 in Figures 19 and 22, to thus firmly hold the ends of the resultant body against outward displacement, and thus entirely enfolding the center core Is with reversely convoluted layers of the intermediate body 7', until a portion of the fold b is brought to the surface of the finished article, as shown at b in Figures 21 and 22. The exposed fold b may be secured to the main body of the completed device, in an manner found convenlent, such as the stap es m, as shown in Figures 21 and 22, or b any other form of fastening means found esirable.

Attention is called to Figures 13 to '18 inclusive which show transverse sections at various stages in the formation of the novel cleaning pad.

The result of the above described 0 rations produces a substantially cylin rical resilient body, which forms a very convenient cleaning pad, adapted to fit comfortably into the hand of the user; and which, by reason of its considerable mass, together with its resilient character, is adapted to readily conform itself to the surface to be cleaned, polished, scoured or the like. When the device is made of a comparatively coarse meshed fabric, it produces a sponge-like body or spongiform mass readily ada ted to take up and hold cleaning fluids and t e like. When made of all metallic mesh fabric, or composite vegetable yarn and metallic mesh fabric, a spongiform body adapted to roduce in use a high degree of abrading e ect is afforded in addition to other advantages already above mentioned.

By reason of the novel method of making, the resultant body of the cleaning pad is securely held together, so that its shape is retained, and so that it will not easily unravel, become stringy, or otherwise lose its original convenient resilient form.

Having thus described this invention, I claim 1. A cleaning device, comprising a resilient substantially cylindrical spongiform body made of an integral sheet of fabric material formed to provide a center core of interfolded layers, and an outer covering about the center core, the end portions of said core and covering being intertwined to provide interlocked shape-retaining end portions, and means for fastening the outer covv ering against displacement.

2. The method of producing a resilient substantially cylindrical pad-like cleaning device from an integral sheet of flexible material which consists in folding said sheet material, diagonally upon itself, rolling the diagonally folded sheet from the fold with two adjacent corners disposed intermediate the ends of the folded and rolled sheet, then inward] foldin the end portions of the diagona 1y folde I lie said corners, and then reversely convolving the intermediate portion of the diagonally folded and rolled sheet about said corners and inwardly folded end portions to envelop the latter and at the same time intertwist the junctures of said intermediand rolled sheet to over-.

body of the substantial y cylindrical mass.

thus obtained.

In testimony, thatI-claim the invention 1 i set forth above I have hereunto set my hand this 10th day of March, 1925.
